desired height between studs.
Center of mounting panel bolt holes
must be in line with 16" studs unless
extra support board is provided.

8. Failure to mount panel properly
can result in severe personal injury,
death or substantial property
damage.

Height of top exhaust center line is distance in
step “b”. Note correct “up” position for right
or left side venting.
